Dynamic item page in Expand Mode or Lightbox

Hi,

I can send data between a dynamic page and a lightbox, but what I am missing here is the URL for SEO purposes. Also, if I use the regular Category to Item page navigation that, would have to go to a totally new page so, the user loses where they were on the category page. This is not a good experience. (Please let me know if I am missing something here)

1- Can I add elements to te expand or fullscreen mode of a gallery using Corvid?

If not then,
2- How can I enable the user to open an item from a gallery in a dynamic category page in a lightbox or expand mode like experience that includes a URL for the item page and would enable the user to navigate back easily to the Category Page? Can anyone help with that?

Thank you in advance!
